Abstract

We characterize multimode second-order nonlinear optical quantum processes by developing a resource-efficient tomography method. The complete information obtained enables the identification of eigenquadratures and the associated amplification and noise properties of multimode quantum processes.

We experimentally characterize multimode nonlinear-optical quantum processes by obtaining the complete information. This full information allows us to factorize the multimode processes, leading to the identification of eigenquadratures and the associated amplification and noise properties.

Scheme for coherent-state quantum process tomography via normally-ordered moments

Masoud Ghalaii, A. T. Rezakhani

Using coherent states in optical quantum process tomography is a practically relevant approach. Here we develop a framework for complete characterization of quantum-optical processes in terms of normally-ordered moments by using coherent states as probes. We derive the associated superoperator tensors for several optical processes. We also show that our technique can be used to determine nonclassicality features of quantum-optical states and processes. Furthermore, we investigate identification of multimode Gaussian processes and show that the number of necessary probe coherent states scales linearly with the number of modes.

Efficient tomography of quantum-optical Gaussian processes probed with a few coherent states

Xiang‐Bin Wang, Zong‐Wen Yu, Jiazhong Hu +2 more

An arbitrary quantum-optical process (channel) can be completely characterized by probing it with coherent states using the recently developed coherent-state quantum process tomography (QPT) [Lobino et al., Science 322, 563 (2008)]. In general, precise QPT is possible if an infinite set of probes is available. Thus, realistic QPT of infinite-dimensional systems is approximate due to a finite experimentally feasible set of coherent states and its related energy-cutoff approximation. We show with explicit formulas that one can completely identify a quantum-optical Gaussian process just with a few different coherent states without approximations like the energy cutoff. For tomography of multimode processes, our method exponentially reduces the number of different test states, compared with existing methods.

Quantum process tomography with coherent states

Saleh Rahimi-Keshari, Artur Scherer, A. Mann +3 more

We have developed an enhanced technique for characterizing quantum optical processes based on probing unknown quantum processes only with coherent states. Our method substantially improves the original proposal (Lobino et al 2008 Science 322 563), which uses a filtered Glauber–Sudarshan decomposition to determine the effect of the process on an arbitrary state. We introduce a new relation between the action of a general quantum process on coherent state inputs and its action on an arbitrary quantum state. This relation eliminates the need to invoke the Glauber–Sudarshan representation for states; hence, it dramatically simplifies the task of process identification and removes a potential source of error. The new relation also enables straightforward extensions of the method to multi-mode and non-trace-preserving processes. We illustrate our formalism with several examples, in which we derive analytic representations of several fundamental quantum optical processes in the Fock basis. In particular, we introduce photon-number cutoff as a reasonable physical resource limitation and address resource versus accuracy trade-off in practical applications. We show that the accuracy of process estimation scales inversely with the square root of photon-number cutoff.
